AMENDMENT NO. 2 TO SCHEDULE 13D

 

Explanatory Note:  

 

This Amendment No. 2 (the “Amendment No.2”) amends and supplements the statement on Schedule 13D and Amendment No.1 to such Schedule 13D filed respectively on February 12, 2021 and August 12, 2022, (collectively, the “Schedule 13D”) with the U.S. Securities and Exchange Commission relating to the Common Stock of Disc Medicine, Inc. (formerly Gemini Therapeutics, Inc.) (the “Company”), by FS Development Holdings, LLC (“FSDH”), Foresite Capital Fund V, L.P. (“FCF V”), Foresite Capital Management V, LLC (“FCM V LLC”), Foresite Capital Opportunity Fund V, L.P. (“FCOF V”), Foresite Capital Opportunity Management V, LLC (“FCOM V LLC”) and Dr. James Tananbaum (and together with FSDH, FCF V, FCM V LLC, FCOF V, and FCOM V LLC, the “Reporting Persons”). Except as specifically provided herein, this Amendment No.2 does not modify any of the information previously reported on the Schedule 13D. Capitalized terms used but not defined herein shall have the same meanings as are ascribed to them in the Schedule 13D, as applicable.

 

On December 29, 2022, the Company completed its business combination with Disc Medicine Opco, Inc. (formerly Disc Medicine, Inc.) (“Disc”) in accordance with the terms of the Agreement and Plan of Merger and Reorganization, dated as of August 9, 2022 (the “Merger Agreement”), by and among the Company, Disc and Gemstone Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of the Company (“Merger Sub”), pursuant to which, among other matters, Merger Sub merged with and into Disc, with Disc continuing as a wholly owned subsidiary of the Company and the surviving corporation of the merger (the “Merger”). In addition, on December 29, 2022, the Company effected a 1-for-10 reverse stock split of its common stock and implemented a reduction in the number of authorized shares of common stock to 100,000,000. In connection with the Merger, the Company changed its name to “Disc Medicine, Inc.” Following the completion of the Merger, the business conducted by the Company became primarily the business conducted by Disc.

 

Under the terms of the Merger Agreement, immediately prior to the effective time of the Merger, each share of Disc’s preferred stock was converted into a share of Disc’s common stock. At the closing of the Merger, the Company issued an aggregate of approximately 12,533,557 shares of its common stock to Disc stockholders, based on an exchange ratio of 0.1096 shares of the Company’s common stock for each share of Disc common stock outstanding immediately prior to the Merger, including those shares of common stock issued upon conversion of the Disc preferred stock (the “Share Issuance”), resulting in approximately 16,923,285 shares of the Company’s common stock being issued and outstanding immediately following the effective time of the Merger.

 

The shares of the Company’s Common Stock listed on The Nasdaq Global Market, previously trading through the close of business on Thursday, December 29, 2022 under the ticker symbol “GMTX,” commenced trading on The Nasdaq Global Market under the ticker symbol “IRON” on December 30, 2022. The Company’s Common Stock is represented by a new CUSIP number, 254604 101. The principal executive offices of the Issuer are located at 321 Arsenal Street, Suite 101, Watertown, Massachusetts 02472.

 

This Amendment No.2 is being filed to report that on December 29, 2022, as a result of the completion of the foregoing Merger and Share Issuance, each of the Reporting Persons ceased to be the beneficial owner of more than five percent of the outstanding Common Stock of the Issuer. The filing of this Amendment No. 2 represents the final amendment to the Schedule 13D and constitutes an exit filing for the Reporting Persons.

 

 

The following Items of the Schedule 13D are hereby amended as follows:

 

ITEM 1. SECURITY AND ISSUER

 

The information set forth in the Explanatory Note is hereby incorporated by reference into this Item 1, as applicable.

ITEM 5. INTEREST OF SECURITIES OF THE ISSUER.

 

The percentages used in this Item and in the rest of the Schedule 13D are calculated based upon an aggregate of 16,923,285 shares of Common Stock outstanding on December 29, 2022, as reported in the Issuer’s 8-K.

	1.	As of the date hereof, FSDH beneficially owned directly 487,025 shares of Common Stock, representing 2.88% of the Issuer’s Common Stock.
(c)		None of the Reporting Persons has engaged in any transaction during the past 60 days involving the Common Stock.
